Video game testers examine new or modified video game applications to evaluate whether or not they perform at the desired level. Testers also verify that different tasks and levels within a game function properly and progress in a consistent manner. Their work entails trying to find glitches in games and sometimes crashing the game completely. Testers keep very close track of the combinations they enter so that they can replicate the situation in order to remedy it. Testers also offer opinions on the user-friendliness of video and computer games. Any problems they find or suggestions they have are reported in detail both verbally and in writing to supervisors. Video game testers act as quality assurance testers who specialize in testing video games.
